Application tiled October 17, 1911. Serial No. 655,253. y

v clear, and exact description thereof.

My invention relates particularly to cars for carrying loose commoditiessuch as grain, coal, gravel, and the like, and it. has for its object tosimplify the construction ofthe ca r as a carrier for loose commodities,to simplify and render more effective the seal and locking device forthe dumping doors, to simplify and vform as a-eompoi'ient,

part of the car as 'a general freight carrier. the grain Adooradjustable in height to meet the usual requirements, and to prevent thelodgme'nt of Water. in thel vicinity of the dump door-.lock

The invention may be 'said to consist of the Aconstruction' and severalcombinations andarrangementsvof parts hereinafter dcsc'ribed and pointedout in the claims.

For full comprehension, however. of my invention reference must be hadto the act-.onipanying ,drawings forming a part of this specification inwhich similar reference cha ra'cters indicate the saine parts, andwherein:

'I

My improved car hasa pair of hoppersm'i" disposed transversely and eachconsisting ot :r pair of verticalwalls 2, 2, and a fixed inclined tioormember, the latter being formed'by the end portions of a plate memberextending transversely to Within coniparatively close proximity of thesides of.

the car, the middle of thismember resting on the center `slland beingshaped tolpresent oppositely facing angular door jambs 4, 4. Itconsists,ppreferably, of a pair of plates 5, 5 'constituting the fixedfloor meinb'ers of the. hoppers, and the d6or-jamb portion isvpreferably formed of a separate metal plate 6 bentto the form required,the edges of all three plates being riveted together and touthe centersill as at- 7. The end edgesot these inclined floor members are attachedto the bottoni edges of the vertical side Walls i?, 2 thus formingchutes, the discharge mouths of which are disposed in angularpositionsvsligblly removed from the perpendici-ilar plane of the sidesof the car. .Relatively small. doors 10 closethe mouths ot' thesechutes, and like these months are when closed in positions inclined onlvslightly from the vertical, u flach dump door consists of the doormember proper 12 with end angies lf3 to ward the door-frame formed bythe fixed diagonal floor member and the vertical walls of the hopper,and a stiii'ening fiange l-t extends along the free edge thereof, thedoor heing hinged to the fixed diagonal tioor member and the edges ofdoor and hopper. floor in juxtaposition and the engaging portion of thedoor and door frame .'propcrties, and consists of a bar 25 journaled inangular brackets 26. fastened` at the 'opposite ends of each door to'the sidesills 2l of "the vunder-framing of the car.-

' Each .bar has'preferably forged thereon a handle 28 anda series ofpreferably three, presser-feet 29 adapted to bear 'upon the /oor andpress ittigntlyagainst the doori jamb formed by an angle .iron 36Afastened 2o tothe underside of the side-sills 27. One of thepresser-feet isformed integrally with the handle,.an d a `bracket 30with holes 31'V therein to receive a retainingicotter pin 32,

is fastened to the door `and affords means .25 for locking thehandle'bar, presser-feet and.

door tightly andi.` etectively closed vagainst. leakage of grain andwith suiiicient strength towithstand the maximum load to which it maybe' subjected when the car isv loaded 30 with Coah-oreandthelike.'.Thesepresserf feet are each preferablyvof return-bendform., as shown, to accommodate the stillening flange of the door anddownwardly inclined flanges '35 presented by obtuse angleirons rivetedtothe outer faces of the side sills :inthe-lower edges thereof. Theselanges serving aswater-sheds protecting the upper edgesof the doors whenclosed and the cotter pinfserves as a means for 40 sealing the door. Thehinges for connectf ing thesefdischarge doors to the inclined ioormembers consist of straps 40 fastened l to the doors and .floor-membersand hinge rods 41 uniting them', and devices distinct from the bingeproper, for providing an' effective grain tight joint between the partsheld in juxtaposition by the hinge consist of coinciding flat surfacespresented by e;

flange 42 upon the Vlicor-.member and-.one ofthe faces presentedA bythe' interior of a pocket 43 in the door formed by bends 44 and 4.5surrounding the flange 4 2, the angular position of which is' such as tobe cleared by the door when swinging. to open '55 position. It is to beobserved that the particular arrangement et these faces prevent thermmodity lodging thereon.

.ln order to prevent leakage of granular` +r-Gais: at the ends oi thedoors.when :it pockets to receive the ilangesll of iheletter are formedin. the discharge edges el the vertical Walls of ihshoppers, ofi'- setnietes 5'.- ing riveted or otherwise rigim. eluted f. one the on" sidesof these c5 wpyls al.: and parallel with the coges thereof,

for the purpose. The pockets providbd by the offset-plates and walls arejustsuiiicient to receive the flanges 13 without space for the leakageof the finest granular substance such as'sand or even Hour, and the 70same effective seal is afforded, as shown above, at the hinged .andlocking edges of the door. Check chains sustain the doorsin properposition when open. ,I

AA serious defect inv cars of this type has been the misfit of the floormembers and the unavailabilityof the grain-doors when required. lovercome these defects by providincr a displaceable `telescopic floor.member atdapted to displace any grain4 and the '8g like left on thecenter sill or other members of the nnderframe on which thesedisplaceable floor members rest. The specific device for the purposecomprises a member 60 made up of tongue-and-groove boards 85 arrangedlongitudinally with relationto theV car, and fastened together by metalbands '69 'on opposite, sides of this door member* and braced by aseriesof angle-irons 61 half of the length -of each of which isv rivetedir: 90 place and the remainder sprung outslightly-jY as at 32 toaccommodate thel extensible mem.- 4 I berto be presenlly further alludedto. This floor member` is hinged to the fixed floor 4members -63 of thecar by means of trun- 95' nions iaste'ned tothe floor by lates 66 to'which theyfare nweldedfsuch p ates beingriveted 'o1' bolted inplace,and a plate 67 of halDf'form `with its angle disposed so v as tobear onthetop of the` side sill and against a threshold stri-p 68 whenthe'member 60 is raised and vthus act asa grain seal, and, at the sametime, serve asa stop limiting the outward movement thereof and taking upsome of the strain which otherwise would be carried entirely by the doorframe in the side of the car. The trunnions are journaled in socketsbeneath Athe contiguous edges of the fixed oormembers. I

in which are mounted ol'set plates :70 con-"1110 y ining the trunnionsbetween them, the side ol the ear-body and thetop of the side sill. The:fixed iioor members are securely fastened-in place by being bolted orriveted as at 75 to the underframing. The free edges 115 of thesemcmbers() are beveled to coincide andj make contact with the diagonaljambs 4, 4, on the center sill. To impart to this. displaccable floormember 60 all theproperties of a grainldoor and therefore 'enable 12o itto aii'ord a large or small loading'opening as required, it is providedwith the eX- tensible member before mentioned which' i's indicated at 80and oftrough form slidably. clasping the member G0 between it and the125 sprung portions of the angle-iron .stifi'eners. This extensiblemember is for use solely as a door part and is telescoped within thelimits of the niain door member 60 when the l lati-.er serves as a floormember. Y

lVith the parts assembled as above described an elfective and strongfloor is pro- -1v1ded for the ca-r as a common freight-car- `llier,-iyhen thegreatest stra-ins are exerted,

and as a graindoor is effective as a grain seal, durablep,lightinweight, and always available, the -tlischarge hoppersanddoors aregrain tight at allpoints and also durable andflightinweight, andthecomplete structure is of suflicient strength to sustain thestrainse'xerted by the heaviest cargoes of loose commodities;furthermore, an ad- `vantageous feature of the enveloping flanges 50.01'the vertical walls f the hoppers and the Hanges on the'door'envelopedthereby,

-is that it is impossible for leakage to occnr ct one finest granularloose commodity owing to the sealing enveloping flanges. The mainmember, 60 of the combined floor and grain-door'is held inverticalpositionV independently ofthe, extensible' section S0 andbracket, by a pair of latches 200 car- I'ied by plates 201 countersunkin the sides properties of thesef 'of the door posts.

The telescopic member is held up by bo'wspring catches 205, rivetedWithin recesses 207 therein, and sockets 206 in the topl of the mainmember of the door are engaged by these catches.

Ido not claim the locking device, the` convertible grain'- doorand floorsections 'for a car, northe features of the door jambe .and particularformation of. the

'doors for engaging 4thejambs lto' afford convertible-flat andhoppf'zr-bottom dumping car structure, as the said inventions form thesubject-matter lof separate applications as follo\\'s:-Car door.locking' def vice, lifted July' 1 1, 1912, Serial No.1; 710,265. '5.0
